The Cartographers’ Guild is a forum created by and for map makers and aficionados, a place where every aspect of cartography can be admired, examined, learned, and discussed. Our membership consists of professional designers and artists, hobbyists, and amateurs—all are welcome to join and participate in the quest for cartographic skill and knowledge.

Although we specialize in maps of fictional realms, as commonly used in both novels and games (both tabletop and role-playing), many Guild members are also proficient in historical and contemporary maps. Likewise, we specialize in computer-assisted cartography (such as with GIMP, Adobe apps, Campaign Cartographer, Dundjinni, etc.), although many members here also have interest in maps drafted by hand.

Welcome to the Guild Carlo. So, if I understand you Carlo, these are not maps that you have created, but that you are drawing on as examples for the kind of mountains you want to end up with. Given that, you want to know how to reproduce such mountains, and what kind of software you need to do so. Is that right? If so, you are looking for either this tutorial, or this tutorial. Each of these will walk you through the process of map creation, including the mountain-building steps, that were used to create the maps you are using as examples.
